New Trier won its first playoff game 30-3 Friday against Lyons Township High School, with plenty of support from the crowd.

The mild weather attracted a crowd of New Trier football fans, including a student group, many of whom were dressed in 1980s hair metal gear, cheering on the team over loudspeakers in the hour before the game began.

The win advances the No. 9 Trevians to the second round of the playoffs, where they will face No. 8 Homewood-Flossmoor at 7 p.m. Saturday, Nov. 7, in Flossmoor.

Billie and Bud Cary, a Northfield couple who said their kids graduated from New Trier several years ago, said they love coming to New Trier football games and seeing the spirit of the crowd.

"We love the student group too," said Billie Cary. "They're very entertaining. It's a great thing to do on a Friday night."

Bud Cary, a 1960 New Trier graduate, said the kind of spirit shown at New Trier football games in recent years shows a drastic shift in attitude compared to decades ago.

"Back in the 1970s, you were square if you came to a game, but now, everyone shows up," he said.

New Trier sophomores Katie Kessler and Ella Preston were preparing under the field lights to cheer on their team's first playoff game of the 2015 season.

"I think it's really exciting now that we're doing well," Kessler said. "It's a really good feeling. We like the adrenaline of the crowd. It makes our job easier."
